soil temperature and moisture variation for the different operating modes of a model energy pile
In this case, not only is the heat distribution within the soil affected, but the moisture is also affected.
In this paper, the effects of intermittent and continuous operation modes of model geothermal energy piles on soil temperature and water content are preliminarily studied.
The experiment carried out 24 hours of continuous work, 16 hours of work, 8 hours of rest, 8 hours of work and 16 hours of rest.
The maximum change in soil temperature and water content is recorded in the nearest place to the pile, and in all operating modes tends to decrease as the radial distance increases.
The results of this study show that the effect of intermittent operation with longer recovery time on the change of soil temperature and water content is lower.
